Y tain new and useful Improvements in Padlocks, of which the following is a specification.

This invention relates to padlocks and it relates particularly, to locks of this kind in which sliding shackles are employed.'

The primary Object of the invention is to provide simple, cheap and easily assembled means whereby the parts for securing and releasing one arm of the shackle of a padlock shall be maintained in proper operative Y position within the lock without necessitating the attachment of such parts to the lock casing, thereby dispensing with extraneous attaching means and the laborincident to securing them in place, and also preventing defacing the outside of the casing by eX- posed screws or rivets. A further object of the invention is to provide a lock of the kind referred to wherein the means for retaining the locking spring and the spring for projecting the shackle from the lock when released, shall be of such construction as to permit of their being punched from sheet metal and of being connected by riveting the parts to each other thereby cheapening the structure and reducing the laborr necessary to secure the parts together. I have further in view the object of so constructing and arranging the means for holding the locking spring and the spring for projecting the shackle from the lock when released, that they together with the springs shall be capable of being yjoined together Y chamber 1n the lock case are two disks 8 and and introduced into the casing in a complete operative position without requiring attachment to the casing by screws, rivets, or the like, which latter means ordinarily not only adds to the cost of material and labor. but results in detracting' from the outward appearance of the lock. I have also in view the production of locking means, and means for projecting the shackle from the lock which shall be of a form to be certainin operation and the parts whereof shall be capable of long use without undue wear.

With these objects in view the invention consists of a padlock having thev generic` and specific features of Y constructionv and, ar-

rangement of the parts substantially as hereinafter described and claimed.

The invention is illustrated in the accompanying drawing in which,

Figurel is'a side elevation of a lock, oneface plate thereof and one of the retaining disks employed being removed, the shackle being shown in a locked position by full lines andin an unlocked position by dotted lines;

. Fig. 2 is a side view of the shackle;

- Fig. 3 is a perspective view showing one of the disks to which the means for retaining the locking spring and the spring for projecting the shackle from the lock are attached; f Fig. l is a perspective view showing the second diskV for securing the operative springs in place; Y

Fig. 5 is a perspective view of the locking spring;l and, L

Fig. 6 is a side view of the key employed.

Fig.'7 is a sectional view of the part-s of my lock in assembled position.

In this drawing l represents the body of the padlock which may be of any desired form and which'has at one side-thereof two openings 2, for the reception of the two* arms 3 and 4 of the shackle 5. The casing has formed therein on the side opposite to that in which the shackle openings are located, a key opening 6 in which is secured a rotatable slotted key disk 7.

9 which are secured together and are separated apart a distance such that when they are placed in the chamber each will be adjacent to an outside face of the lock case.

Secured to the disks 8 and 9 are two plates 10 and ll arranffed parallel to each other and extending transversely of the v lock. Each of these plates has projecting from its edges'nibs 12 adapted to enter corresponding openings in the respective disks and be secured to the latter by riveting the ends. Arranged between the plates l0 and ll is a spring 13 whichis bent back upon itself to spring is of a width corresponding to the point in line with the opening 16 in the plateI of the key. The ends of the plate 11 which f projects beyond the plate 10 has in it an opening 16 through which the lower end of the arm 4 of the shackle projects and by which it is guided in its longitudinal movements.

Extending between vthe disks t8 and 9 at a 11 is a bar 17 having extending from one 4face thereof a stud 18 on which is arranged a coil spring 19 which bears against the end of the arm 4 of the shackle and by which it is moved outwardwhen released from the locking means. The stud 18 may be of any form and may either be integral with the bar, or as herein shown may be a separate piece riveted or otherwise connected to the bar.

' rhe disk 9 has connected to it a projecting lip .2O which engages a portion of the arm 4 of the shackle and which when the parts of the lock are assembled prevents the separation of the shackle from the case of the lock. The lip has formed with it an arm 21 having a reduced end 22 which enters an opening in the disk 8 and to which it is secured by riveting.

The arm 4 of the shackle has a socket 23 formed in its end, such socket being of a size toreceive the coil spring 19 which is normally maintained .under tension and vtends to move the shackle outward from the case of the padlock. The arm is formed a short distance from the end onV the opposite faces thereof with notches 24 of a lengthl corresponding to the width of the locking vspring 13. lVhen the shackle is pushed into the lock the ends of the spring 13 enter'the notches and the ends of the latter form stops against which the edges of the ends of the spring bear and by which the shackle fis held against the longitudinal movement. Above the notches 24 the arm 4 is formed with a circumferential groove 25 into which the lip 20 projects, the parts being so arranged in relation to each other that free rotation of the'shackle arm is permitted and its withdrawal fromv the case prevented. The side of the shackle above the groove 25 v which lis adjacent to the lip 20 is cut away as shown at the point 26 so that when both the arms of the shack are in their openings in the case such c ut away portion is opposite the lip 20 and the latter therefore presents no obstruction to the inward movement of the shackle. When however the shackle is moved outward from the case a predetermined distance to allow the arm 3 of the Y I shackle to be swung away from itsopening in the body, the lip contacts with the lower face of the groove 25 andV checks the outward movement of theshackle preventing the withdrawal of the latter from vthe case. Each of the disks 8 and 9 has extending from one edge thereof a small lip 26 which enters a socket in the inner face of the chamber of thelock. By this means the placing of the disks in order to properly locate the parts carried by them, and means for preventing the turning of the disks in thecase is provided.

In assembling the lock, the plates 10 and 11 are secured to the disk 8 and are attached thereto by riveting the end of the nibs 12, and the bar 17 is also connected to they disk in a similar manner. The spring 13 is placed between the plates 10 and 11the spring 19 is placed around the stud 18, andthe disk with the parts carried thereby is introduced and the ends of the spring are Vforced apart after which the shackle is introduced. The arm 4 of the shackleis passed through the opening 16 in the plate 11, and is moved into the case until checked by the bar 17, at which time the end of the'spring 19 is seated in the socket in the end ofthe arm. The disk is thenintroduced and is secured in place by riveting the nibs extending from the plates 10 and 11 and those extending from the'bar 17 and from the end of the arm 21. Finally the face plates of the lock are arranged outside the disks and are secured'in place in any suitable manner, preferably by spinning the edges of the chamber of the lock over the face plates and in this way a smooth outer appearance free from exposed screws or rivets is presented.

I claim:

1. A padlock comprising a case, a disk arranged in the case, unattached thereto and having transverse plates secured toit, a spring bent back upon itself and arranged between theplates, a shackle having an arml provided with voppositely arranged flattened faces extending between the ends of the spring, a second disk arranged in the case, attached to the first and spaced therefrom, and face plates secured to the-body.
